4. Installation of the thruster
IMPORTANT
Please read these instructions carefully and in their entirety before
starting the installation.
4.1.1.
Drilling tool kit
Makes the tunnel installation very efficient and shortens the installation
time considerably.
Consists of:
Compass for easily locating the tunnel centre spot.
Electric straight grinder including centre rods for cutting the holes in the
hull.
Adapters for all thruster dimensions.
For more information ask your dealer or contact Engbo AS directly.
4.1.2.
Choosing and marking the location
Select a suitable position for the bow thruster.
For best result, make sure that the bow thruster is located as far forward
and as low in the hull as possible. To prevent air being drawn into the
tunnel, the upper part of the tunnel should be at least its diameter below
the surface.
Use an appropriate drawing instrument (refer to your dealer regarding
availability of drawing/cutting tools) to mark the point at which the hole for
the bow thruster tunnel is to be inserted.
Mark out the hole in its entirety on the inside of the hull so as to ascertain
the optimum position for the tunnel.
NB:
Make sure that the tunnel is mounted as transverse in the boat as
possible. After having located the centre spots, check both sides
according to selected reference spots in the hull.
